Since Ford made tops optional in 1909 - 1910 it left an opportunity for aftermarket suppliers to jump in early. This is a classic depiction of a two lever Model T that shows the early location of the rear door handles used on the first 2500 - 3000 cars. Also shown is one of the two styles of top available. This one has the landau arms so that leather straps to the front are not needed.
This is an early Ford print advertisement showing again the pre - 3000 body, this time with the top down.
I have some of those pieces of a top.
How late were the landau bars used.
My 09 has an aftermarket top, no idea of the maker.
